ABSTRACT
The objectives of research were to improved (1) students learning activity in colloid subject used Team Games Tournaments (TGT) assisted by Chemimagz, (2) learning achievement in colloid subject used Team Games Tournaments (TGT) assisted by Chemimagz.
The research was a Classroom Action Research which held in two cycles. Each cycle contained four steps such as planning, acting, observing, and reflecting. The subject of the research was class XI Science 3 of SMA Negeri Kebakkramat in academic year of 2014/2015. Data were obtained by observation, interview, test, quetionaire, and documentation. Qualitative descriptive  used to analize data in this research
The result of the research showed that (1) The application of Team Games Tournaments (TGT) assisted by Chemimagz could improve the student’s learning activity in colloid subject. It proved from the implementation of cycle I and cycle II. In cycle I, the attainment of student’s learning activity  was 92%,  then increased to 100% in cycle II. (2) The application of  Team Games Tournaments (TGT) assisted by Chemimagz could improve student’s learning achievement in the colloid subject. In this research, student’s achievement includes two aspects. Based on test result in cycle I and cycle II, attainment of students learning completion reached up to 83% and increased until 89% in cycle II. Then the attainment of students satisfaction aspect increase from 94% in cycle I to and 98% in cycle II.
